feat(e2e): add Playwright config for Docker/Kamal deployment testing

- Add playwright.docker.config.ts for testing deployed containers
- Add npm scripts: test:e2e:docker, test:e2e:production
- Add e2e/smoke.spec.ts for public pages (no auth required)
- Support DOCKER_URL/BASE_URL env vars for flexible target URLs
- Update docs with E2E testing instructions

Tested against production: 6/6 smoke tests pass

+## E2E Testing Docker/Production
+
+Run smoke tests against Docker container or production:
+
+```bash
+# Test local Docker container (localhost:3000)
+npm run test:e2e:docker -- e2e/smoke.spec.ts
+
+# Test production deployment
+npm run test:e2e:production -- e2e/smoke.spec.ts
+
+# Test custom URL
+DOCKER_URL=http://staging.example.com npm run test:e2e:docker -- e2e/smoke.spec.ts
+```
+
+**Note:** Only smoke tests work against Docker/production. Full E2E suite
+requires the test database setup (see issue rb-myu for details).
+
+See `playwright.docker.config.ts` for configuration details.
+
 ## Future Improvements
 
 - **Litestream**: Real-time replication to S3 (see epic rb-8xp)
